Strange uses for energetic materials


Its kind of interesting to look at chemical literature and see
some of the strange compounds that are found in everyday
procucts.

Here is one that is called "Musk Xylene" which is used as a
fragrence in "fine purfumes" it is a tri nitro xylene derivative.
Due to its poor OB it would probably be difficult to denonate,
but it is strange to find it in a purfume.

http://ec.europa.eu/health/ph_risk/committees/sccp/documents...

di nitro phenol DNP is used by bodybuilders at up to 1 gram
per day for weight loss. It short circuits the electron
transport chain resulting in an increase in metabolism of
30% or more plus a lot of sweating.

I don't think I quite understand why these are "strange" uses for energetic materials?
Simple chemical compounds are part of very many everyday objects and things, and that goes for those, if pure, that are explosive as well.

Take nitroglycerine for example: The use of Nitroglycerine in medicine is something "everyone" knows, and therefore not very exiting. But if one were to find out that they recently started using Nitroglycerine in medicine, every chemist's eye would pop out.
TNT was used as a pigment not too long ago...in its pure state...

I don't know...I just don't think it's very "strange".
Very interesting though on the trivial level :)

Ammonium nitrate can be detonated and is used in explosives. It also is used in agriculture in HUGE amounts. I can buy it at 80% purity (mixed with chalk) in 25 kg bags.

W O W ! . That is absolutely phenomenal, I quote below _

The ‘explosive embossing’ method achieves a resolution in the two-figure nanometer range. “Nobody believed such a thing could be possible,” raves ICT project manager Günter Helferich. Almost any structure, be it wood, leather, textiles or sand, can be rapidly and accurately impressed on metal in perfect detail with the aid of a sheet explosive.

The structures that have to be imprinted into the steel are so tiny that they cannot even be discerned under an optical microscope.

Some low-molecular-weight nitro compounds, and nitrate and nitrite esters, especially nitroglycerine, besides being explosive, are used medicinally in small quantities as vasodilators in the treatment of angina pectoris. Nitrite esters are also used as an antidote for cyanide poisoning. TNT, TNB, and dinitrobenzene are also used as an intermediate in the preparation of dyestuffs (yellow mostly) and photographic chemicals.

Nitrobenzene and nitrotoluene are used in Kerr cells (useful as fast electronic shutters
among other applications) because it has an unusually high Kerr constant.

Pauling lists picric acid as an indicator in the range of pH 0 - pH 2.

Explosives are sometimes placed on top of a large metal plate which is placed on another metal plate when the explosive detonates the pressure and force weld the flat parts together; an effect impossible with conventional methods.

Those chemistry oddities. . .
Picric acid was used as a dye long before its explosive properties were known, and hexanitrodiphenylamine was, at one time, used as a dye called auramine. A golden dye, one imagines!

I remember going through lists of dyes, years ago, hoping it could still be purchased.

Then, some nitro-aromatics have a delicious, fruity almond smell!
As a teenager, encountering gelignite, I wanted to eat the stuff, it smelled so good; looked good too, like a creamy, greasy confection, with those curious-looking little balls in there.

And Henning patented cyclonite as a medicinal compound in 1899, more than twenty years before von Herz patented it as an explosive.
I hear it's also used as rat poison!

So one use was to prolong life, while the other had the opposite effect, as with nitro.

Then there was the woman who found that a tab of viagra placed in her husband's shoe made him limp.

My wife don't need no viagra!

Ooops! I just realised that, given my location, my previous post could prompt some searching questions.
That war's over, hopefully!

Odd for a white (or very nearly so) chemical. Did you mean picric acid?
"hexanitrodiphenylamine was, at one time, used as a dye called auramine"
Again that seems unlikely.
http://www.roguesci.org/chemlab/energetics/hexanitrodiphenyl...
Things that cause skin burns are not generally well tolerated as dyes.
OTOH
http://en.wikipedia.org/wiki/Auramine
seems to be a different compound

Charles E Monroe might have seen the possibilities there a long time ago, and before detasheet!

He found that fragile forms like insects could could be embossed onto steel plate in the minutest detail using explosives.

He used compressed guncotton, but the idea was the same.
And a sculptress (whose name eludes me) in New Mexico makes fascinating explosively-formed works of art!

For me, that'd be the icing on the cake!

I checked COPAE, and you're right, unionised, I got it ass-ways.
It was hexanitrodiphenylamine's ammonium salt, and it was called aurantia.

Both it and picric acid (TNP) were yellow dyes.

I'd say that'd cause loud belches. . .and smoke-rings without cigarettes! 'Fascinating, though!

While I'm at it, I remember something once about some military guy who had an ashtray made of TNT on his desk.

Cast TNT probably, which wouldn't ignite easily, and insensitive enough for a block of it to be sculpted by hammer and chisel.

Can't you just hear the conversations in both cases?

Yeah, that is actually true (I can't cite a reference though)

It was actually the inventor of TNT who had an ashtray made of TNT to demonstrate the insensibility of it, and if I remember correctly, the actual "insensitivityness" of TNT had not yet been properly recorded.

Quite cold to pull a stunt like that :P

'Slightly off-topic, but a question that exercises me from time-to-time is, can cyclonite be safely melted and cast?
Davis gives its m.p. @ 202*C, and says it fumes off @ 290, but doesn't detonate even @ 360.

A match-flame causes it to melt to clear globules before ignition, and its deflagration is a relatively tame affair.
The melted material, though, may be so sensitive that trying it may constitute a death-wish!

I'm still curious, though!

Too bad he didn't also make the Nobel prize out of it.
An awards ceremony in which someone was handed
trophy made of TNT would be interesting, to say the least ;)

The use of nitrocellulose as a plastic before it
was replaced by the acetate and other plastics would also
count as an example of use of an energetic material for
non-explosive purposes. Back in the day, people had terrible
accidents with shirt collars stiffened with the stuff and even
today, we still have archives full of films stored on this
unstable medium.

I had about 5 grams of that in the Lab under water a while back just for that purpose, and then got rid of it when I realised it`s properties (I`m not licensed to own such materials), Pity as it`s the most Crazy Fantastic Yellow you could ever wish for :)

a Low explosive that was used commercially in Film and also plastics like screwdriver handles and car window protection, paints, and snooker balls is Cellulose Nitrate, it still has a place in some everyday objects but often at lower nitration and also stabilised (Camphor is a such a stabiliser).

KCl03 used to be used in cough sweets as a bactericide and NaCl03 besides being a weedkiller (ouch!) is also a plant-growth hormone if used in minute quantities.

The use of nitrocellulose lacquer allegedly downed a large airship when static caused ignition, leading to the hydrogen catching fire.

There are probably many other similar examples around!
